POWER-CHAMBER. y I

To all whom t may concern Be it known that I, JAMES F. SCOTT, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Power-Chamber, of which the following is a full, clear, and exact description.

This invention relates to internal com.- bustion engines and particularly to an im proved power cylinder, and has foran object a provision of an improved construction which will eliminate the necessity for the use of lubricating oilin the cylinder.

Another object in view is to provide a cylinder` which utilizes the ex ansion and contraction of the bodythereo for operating a power membcras, for instance, a connecting rod instead of utilizing the conventional piston. l,

A .still further object in view is to provide an improved power cylinder which u'tilizes flexible plates and bracing means as` sociated therewith for transmitting power produced in the cylinder by an explosion of combustible gases. l

In the accompanying drawings, Figure 1 is a side view of a cylinder embodying the invention, a" supporting frame being shown in connection therewith for moreclearly illustrating lhow the cylinder operates; Fig.l

2 is an enlarged fragmentarysectional view through part of the cylinder shown in Fig. 1, the position of the parts being shown greatly exaggerated; and Fig. 3 isa fragmentary sectional 4View through Fig. 2 approximately on line 3-3.

Referring to the accompanying drawings by numerals, 1 indicates the cylinder embodying the invention and 2 any suitable framework associated therewith. The upper part of the cylinder 1 isconnected with what might be termed a head 2' which is adapted to receive in openings 3 and 4, inlet and outlet valves, while a suitable spark plug 5 is arranged at a convenient point for ignitiiig the gases forced into the cylinder. The position of the parts forming cylinder 1 shown in Fig.i 1 is a greatly exaggerated for the purpose of illustrating how the same expands and contracts for operating the connecting rod 6 which is connected with the crankshaft 7 in the usual manner.

In Figs. 2 and 3 will loe-seen details of the particular construction of the cylinder, the

various parts being shown greatly exaggerated especially in Fig. 2 for the purpose of illustration only. In practical construction, the expansion and contraction of a pair of disks approximatelysix inches in diameter, will be probably about one-eighth of an inch instead of the large expansion shown in Fig.-

2. As shown in this figure there a`r`ey pairs of disks 8 and 9 which form the bellows construction of the cylinder 1 shown in Fig. 1. A ring 10 is provided with an'internal slot in which the outer edges 11 and 12 of -the disks or plates 9 and 10 are forced. As

shown in Fig. 3, the ring 10 may be divided and secured together by a suitable bolt 13. 'In forming the ring 10 a groove portion 14 is'provided on one Iside and a groove portion 15 on the opposite side for seating the ends 16 of the bracing ribs 17. The inner ends 18 of ribs 17 contract at the center or hub part of the cylinder except .the ribs at the end of the cylinder, where they contact with a suitable nut 19, as shownin Fig. 1. A sleeve 20 threaded exteriorly is provided on which nuts 2 1 and 22 are mounted and pinch the inner ends or vflanges 23 together.

In order that the parts may fit properly together, tubular portions 24 are provided on each of the disks 8 and 9 so as to provide a proper bearing for seating the ends 18 of the bracing ribs 17. It will be observed that the disks or plates 8 and 9 arecomparatively thin Flexible sheets formed of sheet metal of any desired kind. In forming the disks or diaphragms the same Aare formed slightly dished and the action or vibratory movement of the disks or diaphragins is never more than the movement from the center line of the fiat plane to the limit of the dished disk portion. The disk, instead of being dished, may be corrugated in rings to aid in the movement thereof. The idea of forming the disks or diaphragms dished or corrugated is to arrange the Ifabric-or construction of the disk so as to subjecl'the same to no strains that will tend to disintegrate the disk. Metal disksand also other materials may-vibrate or bow to a certain extent without injuring or stretching the molecules of. which the particular material is made and when inoving or vibrating to this extent therewill be no injury to the material. If the vibration is such asl to stretch the molecules the body or piece of material composed of those vof diaphragms, ,l lbe expanded by iii molecules willsoon fall apart or disintegrate. ln iiormingthe disks or diaphragme embodying' part otthe invention this law ol :materials is observed by dishingor corrugating the diaphragzjms and then allmvingr the diaphragms to more only a limited extent.

In operation, when the charge has been drawn into the cylinder l and compressed, the spark plug 5 will ignite the (.onibustible matter which, when the saine explodes, will cause the various plates 8 and 9 to more apart centrally or expand as bellows. Each pair ol plates, as heretofore described, will usually expand slightly. but where a large number of plates arc used a comparatively large thrust is given to a power member, as for instance, connectingrod G.' Theylinder may be guided in its movement by any desired means, or have a cross head at the free end so that there will be no twisting of the various plates or disks 8 and 9 or oi any of the other parts. t will be observed that this construction and arrangement is very desirable for explosire engines as aproper four-cycle movement is produced for drawing in` fresh gases, forcing out the burnt products of comlmstion and' compressing the gases after being,` drawn in previous t0 an explosion. After an explosion the return or collapsing' of the plates or bellows construction. will naturally force out all of the burnt products o-con'ibustion and the neXt movement will act as an intake in the usual manner of a four-cycle engine. By this construction and arrangement power is produced and transmitted toa point of utilization without the necessity or even a desirability of supplying the cylinder with lubrieating oil, which oil is usually very troublesome in 'that it makes an undesirable deposit in the cylinder, when a comlniratire large amount has been placed in the cylinder'.

Haring lthus described my invention l claim as new, and desire to secure by Let.
